The AST710 offers some solutions to cope with this situation.
Basically these solutions boil down in transporting Public IP
addresses transparently through the AST710 towards a device
where a more advanced NA(P)T can be performed.
Two solutions are described in the following paragraphs:
Via the PPP to PPTP Relay
"
PPP to DHCP Spoofing.
"
You might consider the following setup below:
Step
Action
1
Install a second Ethernet PC NIC, next to the existing Ethernet
PC NIC, in a PC.
2
Install an OS on this PC that has routing capabilities, e.g. Windows
NT, UNIX, Linux, etc.
3
Install on this PC a NAT/PAT package that supports all TCP/IP
protocols.
Now this PC can act as some 'home gateway'.
4
Connect an Ethernet port of the AST710 to one of two PC's Ethernet
PC NIC.
5
Connect your local LAN to the second Ethernet PC NIC.
By setting up a PPTP tunnel from the 'home gateway', the Public IP
address is transported transparently through the AST710 to end
up in the 'home gateway' where more complex NAT and/or PAT
operations can be performed.
